Hi Hello! everyone.
in this fashion API changes these days, I found that debian and
winbuntu old lasted revisions, has old libpng 1.2, especialy lenny
with 1.2.22, which means that the patchs for libpng 1.4 support on qt3
for trinity can make impossible compile into Debian squeeze, testing
inlcusive, as win-buntu 9.XX, it should be modified to use a macro
-LIB_PNG_14 or something similar .. I do not remember how to work with
this but if I can do for the weekend..
If some body can do that , please change the patch for use optionaly
both library versions...
If i can resolve all issues, i do a qt3 3.3.c tar gzipped release
alternate for ready download in public, for easy acces to novice
developers
